            <a name="what_is_tar_file"></a>TAR is
a popular archiving
format, mainstream for data backup and distribution purpose on Unix and
Unix-like systems, as BSD, Linux and derivates. In use since early Unix
versions, predating integrated archiving and compression formats like
zip and rar, it
was
later standardized by POSIX-1.1988 and POSIX.1-2001. Tar packages are
sometimes referred as <a name="tarball_definition"></a>"tarballs". <br>
            <a name="tarbomb_definition"></a>"Tarbomb" refers to a tar
package
purposely built to spam extraction directory with a large number of
files, effect that can be avoided by moders archivers simply employing
"extract to new folder" option.<br>
            <br>
            <h3><span style="font-weight: bold;">Maximum size of a TAR
file</span></h3>
Current POSIX.1 2001 revision of the tar standard removed the old
limitation of 8 GB of maximum archive size for tar archives defined in
POSIX.1 1988 standard<br>

            <span style="background-color: rgb(255, 238, 221);"><a
 name="tar_extension"></a>TAR
file format doesn't
feature native data compression</span>, so TAR archives are often
compressed
with an external utility like, but not only, <span
 style="font-weight: bold;">GZip</span>, <span
 style="font-weight: bold;">BZip2</span>, <span
 style="font-weight: bold;">XZ </span>(using
7-Zip / p7zip LZMA / LZMA2 compression algorithms), <span
 style="font-weight: bold;">Brotli</span>, <span
 style="font-weight: bold;">Zstandard</span>, and similar
tools to reduce archive's size, i.e. for more compact backup, or
smaller software distribution package.<br>
            <a name="tgz_tbz_extension"></a>Resulting compressed files
can be found named with single extension, e.g. TGZ, TBZ, TXZ, TZST, or
with <a href="files-with-double-extension.html">double file extension</a>,
e.g. <a name="tar.gz_tar.bz_extensions"></a>TAR.GZ, TAR.BR, TAR.BZ2,
TAR.XZ, TAR.ZST.<br>
Adding items to a tarball before compression stage is quivalent to
using <span style="font-weight: bold;">solid compression</span>,
which can be beneficial for optimizing output size.<br>
Similarly, TAR also does
not natively support cryptography, but it is possible to compress the
TAR package with a compression format providing <a

Tar format features extremely fast speed: archiving to TAR file is
equivalent - in speed - of
merging files, faster than raw file
copy as the process avoids overhead of creating a new&nbsp; filesystem
entry for each file. If compression is applied in the pipeline of the
job, it will be likely the speed performance limitating factor.<br>
